### How could oxygen levels have ever been higher if there is so little carbon dioxide present?

The assumptions you state are: Oxygen only exists in the atmosphere, as either O2 or CO2 Carbon only exists in the atmosphere as CO2 and above surface in the form of organic matter Oxidization of ...

### Coriolis effect and Cyclones

As the earth rotates, when air moves from near the poles towards the equator, the radius of that part of the earth is larger, which means, the ground is moving faster and the air lags behind. When the ...

### How could oxygen levels have ever been higher if there is so little carbon dioxide present?

It doesn't go anywhere, you don't need CO2 production to loose oxygen. photosynthesis is water + CO2 into O2 and sugar. In this case the sugar is mostly cellulose. what happened in the carboniferous? ...

### How could oxygen levels have ever been higher if there is so little carbon dioxide present?

Where did all the CO2 go? Shell organisms stored it in the sediments and rocks in the form of CaCO3. This is known as the main sink of CO2. There are other C sinks on the Earth, but lithosphere is ...

### Why does Earth's atmosphere have a whiter color near the horizon?

This pair of pictures shows that the sky is not only becoming more whitish. It also becomes more greenish. On the left is a picture of a typical winter scene. On the right a filter is added, its ...

### Do I understand pressure coordinates in the right way?

In pressure coordinates it is common to use $\omega$ as the vertical velocity component instead of $w$ as in cartesian coordinates. Obtaining the velocity components in the pressure coordinate system:...

### Estimating atmospheric vertical motion from 3D fields in WRF output

After a bit of digging, it seems that vertically integrating the continuity equation in pressure coordinates (shown above) is a sound approach for estimating vertical motion in numerical model output ...
